Rubin Kazan will look to preserve their unbeaten record when they tackle Partizan Belgrade in the final match of Europa League Group H.
The Russians have already qualified for the last 32 as group winners after a draw and four consecutive victories, and face a Partizan side who cannot progress to the knockout stages.
Rubin's record places them alongside Fenerbahce, Metalist Kharkiv and Lyon as one of the four most successful sides in the group stages of this year's competition.
And everything would point to the 2012 Russian Super Cup winners extending that unbeaten run in Serbia.
Rubin dominated their meeting with Partizan earlier in the campaign, winning 2-0 with goals either side of half-time from Gokdeniz Karadeniz and Aleksandr Ryazantsev.
Partizan have never beaten Russian opposition.
Rubin won the group with one match to spare following their 3-0 victory over Inter Milan on November 22, which was sealed with two late goals from the Venezuelan Jose Rondon.
Although Partizan are out of the running for European honours, the club head into their winter break top of the Serbian league with 12 victories and a draw from 15 games.
``Clearly, Partizan is the best side around and we made a step forward this season compared to last one by qualifying for Europa League,'' said Partizan coach Vladimir Vermezovic, who also hit back at his critics.
``It seems we are top of the pile only because others are weak - no, the truth is we are the best side around.
``I would have gladly taken this six-point advantage at the beginning of the season.''
